Hello Edu,
I am very happy to hear that you did such an ROI for half a year! I can tell you that this is a great result! Good job!
As you know from my courses I like to use M15, M30, and H1. Now, in some of the courses, I show M1 and M5 but these EAs are always filtered with longer time frames. Basically, I use FSB Pro to place LTF filters in the EAs.
